Anal dilatation is a medical procedure that involves the gentle stretching of the anus. This technique is employed to address conditions characterized by excessive tightness of the anus, such as anal stenosis and anal fissure. Additionally, it is utilized in the treatment of hemorrhoids. Typically, anal dilatation is performed while the patient is under general anesthesia to ensure comfort and minimize discomfort during the procedure.
In certain anal disorders or as a result of repeated anal penetration, a phenomenon known as reflex anal dilatation can occur. This refers to the dilation of the anus in response to local contact or stimulation. It is a response that may manifest in specific anal conditions or situations involving repetitive anal penetration.
